Microsoft's %Appdata% directory is a security nightmare in my opinion. Ideally applications should only have access to their own directories in %Appdata% by default. I recently came across a python script on GitHub that allows to decrypt passwords the browser stores locally in their %Appdata% directory.

"AppData" is where user specific application data is supposed to be stored. "The Registry" is where application configuration is supposed to be stored.

Making it easier / less work for more devs to do the right thing doesn't seem like an inappropriate request. If users are misusing your system, there are other solutions than RTFM

Earlier quoted context omitted.

AppData is specifically where apps store data, and there are and were plenty of legitimate examples where you want some code to access data from an app in there. The entire point is that it is not meant to be a secure location, was never meant to be a secure location, has no intended security features etc. If you store your passwords in a text file on the desktop, that is also insecure but you would be wrong to say N…

Regardless, full unrestricted disk access for all users and code is insecure.

It isn't full unrestricted disk access for all users and all code. Any OTHER user, or code running with that user's permissions cannot access YOUR appdata directory. The appdata stuff was the running user's appdata. They already had total control of the user's machine, and in fact, had control of that user's domain administrator! This attack is only possible if you have control of the user's domain administrator AND data access to the user's machine so that you can use both the locally stored Bitwarden data AND the domain's backup decryption keys. The phone OS model wouldn't work here. The security compromise happened when the domain administrator account was breached.

>What ruins everything is overzealous and/or ignorant programmers who don't take any pride in their work

uh you mean overzealous product managers and business owners who never let programmers take their time on anything because quality doesn't matter?

why would I take pride over my employer's property? lol if the code he buys from me is bad, that's his problem, especially since I have to stick to his timelines and am not given sufficient equity and agency to feel ownership over the project.

you know what makes programmers lose their desire to take pride in their work? getting blamed when we're ordered to cut corners, or implement bad designs. fuck right off with that, we're not the ones in power.

I'm not so sure I completely agree with you about .ini files. I rather miss them. Some people have regarded the registry as a mistake, or at least an over-reach. I like the ability to edit .ini files and make them understandable.

Maybe the compromise solution is to put the user-relevant portion of the .ini file in %AppData%.

So - the moral of the story is to never use Windows?

Can't blame the programmer for that - Windows shouldn't allow the programmer to do stupid shit

Simple maybe. Coherent, no.
